Aland-Elbe-Niederung, Nature reserve in Saxony-Anhalt, Germany.

The Aland-Elbe-Niederung is a 6,009-hectare nature reserve in Saxony-Anhalt, protected since 16 June 2009. It follows the meandering Elbe from kilometre 473 at the Lower Saxony border to kilometre 431 near Werben, and the Aland from its mouth to northeast of Seehausen. The reserve is dominated by extensive grassland on moderately wet to wet sites, softwood and hardwood floodplain remnants, numerous oxbows, flood channels and damp hollows, with occasional inland dunes.

The reserve was officially established in 2009 by merging two previously protected areas, the Garbe-Alandniederung and the Elbaue Beuster-Wahrenberg, into one larger conservation zone. This consolidation created a more unified space for protecting the river valleys and their wildlife.

The reserve's name comes from the Aland river and the Elbe lowlands it protects. The Hohe Garbe, an Elbe loop on the former inner-German border, kept one of the largest hardwood floodplain forests below Magdeburg because the border kept forestry out. The grassland is mostly farmed intensively, with some areas grazed extensively.

The reserve lies within the Middle Elbe Biosphere Reserve, stretching along the Elbe from kilometre 473 at the Lower Saxony border to kilometre 431 near Werben, and along the Aland from its mouth to northeast of Seehausen. Large parts follow the rivers' natural dynamics and are flooded at high water, so check water levels before setting out. The Hohe Garbe floodplain forest is partly cut off from the river by a dike that is to be removed.

The Hohe Garbe, an Elbe loop at the Lower Saxony border, kept one of the largest and most important hardwood floodplain forests on this stretch of the Elbe below Magdeburg because it lay on the former inner-German border. Its high share of old and dead wood is to be reconnected to the river by removing a dike, which also creates extra flood retention space.
